I'm still trying to figure Billings out, but I would like to send out one invoice for multiple projects to one client. Is this possible?

Not specifically, but you can drag slips from multiple projects into one project and then send an invoice from that project.

Jill,

I just wrote a post about this to another guy. Maybe it'll help you too?

I knoticed that Billings 3 indeed supports multiple projects in one invoice, but is there a way to make some sort of visible 'divisions' per project in the invoice? Can anyone point me in the right direction on how I would do this in my Invoice template? BTW, this truely is an astounding app.

The best thing to do this is to sort by the Project column in the "Slips" tab within the "Send Invoice" window.

And Thanks for the compliment!
